System Integration 
 
 Roadster/Mirage S+ User’s Manual E-1 
The GPIO (General Purpose Input/Output) connector located on the input panel 
provides a flexible method of interfacing a wide range of external I/O devices to the 
projector. There are 7 GIO pins available on the 9pin D-Sub GPIO connector, which 
are configurable via RS232 commands. The other two pins are reserved for ground 
and power – see table below for pin identification.

By using the GIO command, you can also set the state of each pin as high or low. By 
default, the state of each pin is high. The voltage applied to pins in the high state is  + 
3.3V. 
Example 1.
 Turn room lighting on when the projector is turned off. (Assumes a 
control/automation unit is configured to turn the lights on when pin 2 of its input goes 
high.) 
(GIO C2 O)   Set pin #2 configuration to output  
(GIO 2 H)  Set pin #2 to high (state)...
